`aliases` is a tool for resolving command dependencies with containers.
* YAML-based command definition
* Version of command with the environment variable
* Call another dependent command from the command
## Install
```
$ go get github.com/k-kinzal/aliases
```
## Get Started
**~/.aliases/aliases.yaml**
```
/usr/local/bin/kubectl:
image: chatwork/kubectl
tag: 1.11.2
volume:
- $HOME/.kube:/root/.kube
- $PWD:/kube
workdir: /kube
/usr/local/bin/alpine:
image: alpine
tag: 3.8
volume:
- $PWD:/work
workdir: /work
dependencies:
- /usr/local/bin/kubectl
```
```
$ eval "$(aliases gen)"
```
or
```
$ eval "$(aliases gen --export)"
```
Using the option of `--export` can be used as a command instead of an alias.
## CLI
```
$ aliases --help
NAME:
aliases - Generate alias for command on the container
USAGE:
aliases [global options] command [command options] [arguments...]
VERSION:
v0.5.1
COMMANDS:
gen Generate aliases
run Run aliases command
home Get aliases home path
help, h Shows a list of commands or help for one command
GLOBAL OPTIONS:
--config value, -c value Load configuration file
--home value Home directory for aliases [$ALIASES_HOME]
--verbose, -v enable verbose output
--help show help
--version print the version
```
## Version Environment variable
If `/usr/local/bin/kubectl` is defined, you can specify the version in the environment variable with `_VERSION` in the suffix with `kubectl` in the file name capitalized.
```
$ KUBECTL_VERSION=1.11.3 kubectl get all
```
When version environment variable is specified, a command is executed by overwriting `tag` defined by YAML.
## Expand Environment Variables
```yaml
env:
$ENV1: $ENV2
```
```yaml
volume:
- $ENV1:$ENV2:rw
```
```yaml
user: $ENV1:$ENV2
```
Environmental variables expand with parameters expressed like this.
`Env1` expands at the timing when `aliases` generates a command.
`Env2` expands at the timing when you executed a command generated by `aliases`
## Expand commands
```yaml
tty: $(if tty >/dev/null; then echo "true"; else echo "false"; fi)
```
```yaml
volume:
- $(helm home):/root/.helm
```
When you enclose the command with `$(...)`, the `STDOUT` of the command is set as the parameter.
Command expanded at the timing when you executed a command generated by `aliases`.
Note: Always execute the generated command on the machine (host or docker) that executed the alias.
## Special Environment Variable
`$PWD` is a special environment variable.
The `$PWD` specified on the left always points to `$PWD` of the host.
## Extend entrypoint
```yaml
/usr/local/bin/helm:
image: chatwork/helm
tag: 2.12.3
volume:
- $HOME/.helm:/root/.helm
- $PWD:/helm
workdir: /helm
dependencies:
- /bin/bash:
image: bash
tag: 5.0.2
- /bin/curl:
image: byrnedo/alpine-curl
tag: 0.1.7
entrypoint: |
#!/bin/sh
if [ -f $(helm home)/plugins/helm-import ]; then
helm plugin install https://github.com/k-kinzal/helm-import --version v0.2.1
if
helm "$@"
```
If you want to extend `entrypoint`, please define a string with shebang in `entrypoint`.
NOTE: Please understand that extend entrypoint is less reproducible. It should be included in the docker image if possible.
## Dependencies commands.
`aliases` can define commands that depend on commands.
```yaml
/usr/local/bin/sops:
image: mozilla/sops
tag: a2d0328e35e6e37b51f3ad468dc6f213c7b44014
env:
AWS_ACCESS_KEY_ID: ${AWS_ACCESS_KEY_ID}
AWS_SECRET_ACCESS_KEY: ${AWS_SECRET_ACCESS_KEY}
AWS_PROFILE: ${AWS_PROFILE}
AWS_DEFAULT_REGION: ${AWS_DEFAULT_REGION}
volume:
- $PWD:/sops
workdir: /sops
/usr/local/bin/helm:
image: chatwork/helm
tag: 2.12.3
volume:
- $HOME/.helm:/root/.helm
- $PWD:/helm
workdir: /helm
dependencies:
- /usr/local/bin/sops
- /bin/bash:
image: bash
tag: 5.0.2
- /bin/curl:
image: byrnedo/alpine-curl
tag: 0.1.7
```
For dependency, reference to another command defined or define command.
If you want to define a command that can only be called from a command, please recursively define the dependency.
Also, parent commands inherit dependent parameters.
```bash
$ AWS_ACCESS_KEY_ID=xxx AWS_SECRET_ACCESS_KEY=xxx helm secrets enc ...
```
If the same parameter exists, the parent parameter takes precedence.
## How to debug aliases
If you do not get what you expected, please use the `aliases run` command.
```bash
$ aliases run -it --entrypoint '' [command] sh
```
`aliases run` command overwrites the option of your defined command and executes it.
```bash
$ aliases --verbose run -it --entrypoint '' [command] sh
docker run --entrypoint "" --interactive --network "host" --rm --tty [your image] sh
```
If you want to show the docker run command, please specify the option of `--verbose`.
## for CircleCI
`aliases` supports [CircleCI Orb](https://circleci.com/orbs/registry/orb/k-kinzal/aliases).
You can quickly execute precisely the same commands on local and CI.
```yaml
version: "2.1"
orbs:
aliases: k-kinzal/[email protected]
jobs:
aliases:
machine: true
steps:
- checkout
- aliases/install
- aliases/gen
- run: [your command]
workflows:
version: 2
aliases:
jobs:
- aliases
```
However, since A uses privileged and volume, please use [Machine Executor](https://circleci.com/docs/2.0/executor-types/#using-machine).
